Hi teresaYB,
I'm Dyari. Thanks for reaching out. I will be happy to assist you in this regard.
Closed captions let you read the words that are spoken in the audio part of a video or television show. When closed captioning is turned on, closed captions are usually displayed at the bottom of the screen. Closed captions are often used by people with hearing disabilities and by viewers who would rather read than listen to the audio portion of a video.
To turn on closed captioning:
1-Right-click or tap-and-hold anywhere on the video. A menu bar will appear at the bottom of the screen. If closed captioning is available, a CC icon will be displayed.
2-Tap or click the CC icon. Tap or click the language you want to see closed captions in. Closed captioning will now appear on your screen.
If closed captioning is not available for the video, a pop-up window will display “Not available.”
